<h1 class="topictitle1">Step 2: Adding a Storage Device</h1>
<div><p>Before backing up or restoring a NAS file system, add a storage device where the NAS file system to be protected resides to the <span>OceanProtect</span>.</p>
<div class="section"><h4 class="sectiontitle">Context</h4><p>The <span>OceanProtect</span> can protect a NAS file system on the following storage devices:</p>

</div>
<div class="section"><h4 class="sectiontitle">Precautions</h4><ul><li>If a storage device is earlier than OceanStor Dorado 6.1.3, a NAS file system cannot be discovered or protected by adding the storage device. Instead, a NAS share needs to be registered to protect the NAS file system. For details about how to register a NAS share, see <a href="en-us_topic_0000002200046089.html">(Optional) Step 5: Registering a NAS Share</a>.</li><li>If a storage device is OceanStor Dorado 6.1.3 or later, OceanStor 6.1.3 or later, OceanStor V700R001, OceanStor Dorado V700R001, or OceanProtect 1.3.0 or later, ensure that the activated license of the storage device contains <strong>HyperReplication (Remote Replication)</strong>.</li></ul>
